The 19th century.
Dmitri Mendeleev is credited with creating the first periodic table of elements in 1869 after noticing a recurring pattern of properties when arranging elements by atomic mass. Johann Wolfgang had no direct involvement in the discovery of the periodic table.
Dmitri Mendeleev did not discover the noble gases as they were not known at the time he created the periodic table. The noble gases were discovered later by other scientists. Mendeleev's periodic table focused on arranging elements by atomic mass and properties to show periodic trends.
Joseph Priestley did not contribute directly to the periodic table. He is known for his discovery of oxygen and several other gases, as well as his work on the chemistry of combustion and respiration. The periodic table was developed by Dmitri Mendeleev in 1869 based on the properties of known elements at the time.
It is named The PERIODIC TABLE. The periods being the horizontal rows The groups being the vertical columns.
mendeleev
Mendeleev discovered old periodic table. He arranged elements in order of atomic masses.
The 19th century.
he drew up a table that grouped elements according to their atomic weights, his table became the basis for the periodic table of elements used today.
something to do with protons and stuff.
it's presence is known from ancient times.
Ancient times since 6000 B.C.
Dmitri Mendeleev published his periodic table in 1869.

he formulated an early version of the periodic table based on atomic mass
Mendeleev invented the legendary periodic table and their is a university and chemical element named after him.
